Forall practical purposes this armits the use of a single type of fixturefor rangement of the radius arms with the offset 5 various angularitiesofvthe spur line with swinging runners works just as well as respect tothe main line and hence it is not though the points of the swingingrunners necessary to have numerous patterns or dies did actually swingon an arc whose center to take care of all desired angles. was at thepoint of the main runner.

In the drawings: The main plate is provided with a pair of 50 Fig. 1 isan inverted plan view of a frog. segmental slots j throug which engage te Fig. 2 is a side elevation of the same. bolts 70 by which the swingingrunners may Fig. 3 is a section on the line 3-3 of be clamped tightly inany given position of Fig. 1.

It will be apparent that the main or stationary runner can be removed byloosening and removing the bolts 0 while the swinging runners can beremoved by taking out the bolts 7c and the pivot bolts The pivot bolts2' also in connection with the bolts it serve to hold the pan or thewear plate 0 in place. Hence this pan'may be easily removed when itwears out. All these adjustments and removals can be made without in anyWay altering the support of the main plate upon the guy wires.

In Fig. 3, theclamp for the trolley wire is shown. One trolley wirepasses out through the opening in the top of the main runner across thetop of the supporting plate and through the center blocks into one ofthe adjustable runners. The other wire passes out of the adjustablerunner and into one of the clamping blocks and the end is'then usuallyturned around and used as a guy wire to one of the poles. The clampingblocks are forced down against the wires by the nuts 2 engaging againstthe clamping bars.

I have illustrated my invention in connection with. a trolley wire frog,but obviously the. same is adapted for a crossing, or cross-overconstruction, with a few minor modificationswhich, will be obvious. 1What I claim is:

1. A troll'eywire fixture, having in combination a main plate, and'oneor more runners removably secured-to the under side of the main plateand. comprising each a body portion and an :end piece clamped togetherto .hold the trolley wire to the runner- A trolley wire fixture, havingin combination a main plate.-a plurality of runners. removably. securedto. the under side of the main. plate, and a wear piece secured to theunderside ofthe-main plate and removable when the said runners have beenremoved trom the mainplate.

3. Aitrolley wire fixture, having in com.- bi-nation. a main plate,plurality of run- 11ers. bolted... to the underside of the main plate.so-the samecan be. removed without disturbing the supports of themaintplatepand awear piece secured to the under side of the main plateand which can be removed when the runners are removed without disturbingthe supports of the main plate.

4. A. trolley wire fixture, having in combination, a main plate, a main.runner supported on the said plate, and one or more swinging runnerssupported on the main plate;an d adjustable on arcs which approximate a,coincidence with respect to an arc Whose center is-at the pointof themain run- 5. A trolley Wire fixture, having in combination a main plate,a stationary or main runner supported on the main plate, and one or moreswinging or adjustable runners supported on a radius arm on arms whichhave their center or centers closely adjacent the side or sides of thepoint of the main runner but sufliciently spaced to permit clearance forthe flanges of the trolley wheel.

6. A. trolley wire fixture, having in comination a main plate, a mainrunner supported by the same, and a swinging or adjustable runnersupported on a radius arm whose center is closely adjacent at one sideof the point of the main runner, the swinging runner being offset at oneside of the radius arm so thatthe point of the swinging runner inswinging through an arc approximates an arc whose center wouldb'e at thepoint of the main runner.

T. A trolley'wir'e fixture, having in combinati'on a main supportingplate provided with a segmental sl'ot,'a main or stationary runnersupported on the under side of said plate, a radius arm supportedadjacent the point of said runner on a pivot, a swinging runnersupported on said radius arm atone side thereofso that the point of saidswinging runner approximates an arc Whose radius would have its centerat the'point of the main runner, and a bolt passing through said radiusarm and through said segmental slot in the main plate fora'djustablysecuring said swinging runner on the said main plate;

8. A trolley wire fixture, having in combinationv a main plate, astationary runner supported on the main plate, a removable wear piece orpan bolted to the underside of the main plate, a radius arm boltedthrough the main plate at a point closely adjacent the point of the mainrunner but at one side thereof, and a swinging runner supported on saidradius arm at one side thereof, and in such a way that the point of therunner in swinging'upon the pivot of the radius arm swings through anarc ap proxiinati ng an arc Whose radius would have its center at thepoint of the main runner; i

A troley wire fixture, having in combination a main. plate, a stationaryrunner supported on said plate, and one or more angula'rly adjustablerunners supported on the main plate and each bodily adjustableindependently of'any other runner on a swinging radius having its centerbeyond the point of the runner and near the point of the stationaryrunner.

10. A trolley wire fixture, having in combination a main plate providedwith one or more segmental slots, a stationary runner supported on. saidplate, one or more'angu larly adjustable runners, each of which jiswhich is removably bolted to said plate through a segmental slot andadjustable with respect to the stationary runner by loosening thebolting means and moving and bolting the runner again through saidsegmental slot, said adjustment being only on a swinging radius havingits center beyond the point of the adjustable runner and near the pointof the stationary runner.

11. A trolley wire fixture, having in combination a main plate providedwith one or more segmental slots, a stationary runner removablysupported on said plate, one or more angularly adjustable runners, eachof bolted to said plate through a segmental slot and may be removed fromsaid plate without disturbing its support, being angularly adjustablewith respect to the stationary runner by loosening the bolting means andmoving the runner and then again tightening the bolting means, saidadjustment being only on a swinging radius having its center beyond thepoint of the adjustable runner and near the point of the stationaryrunner.

12. A trolley wire fixture, having in combination a main plate providedwith one or more segmental slots, a stationary runner removablysupported on said plate, one or more angularly adjustable runners, eachof which is removably bolted to said plate through a segmental slot, andangularly adjustable with respect to the stationary runner by reason ofsaid nection with the. main plate, and a wear plate removably bolted tothe under side of said main plate and removable with the runners withoutdisturbing the support for the main plate.

In testimony whereof, I have hereunto affixed my signature.
